WATER-CLosET.

SPECIFICATION forming part of Letters Patent N0. 440,030, dated November4, 1890.

Application filed May 12, 1890. Serial No. 351,503. (No model.)

To @ZZ whom t may concer-7c:

Be it known that I, HENRY C. HART, of Detroit, in the county of IVayneand State of Michigan, have invented a new and useful Improvement inWater-Closets, of which the following is a specification.

My invention consists in an improvement in water-closets designedprincipally for railway-cars and for other places in which the supply ofwater is limited, and where only a measured quantity of water is to beused with each use of the closets.

Figure l is a side elevation, partly in section. Fig. 2 is a frontelevation. Figs. Sand t are enlarged partial elevations similar,respectively, to Figs. l and 2. Figs. 5 and o' are vertical sectionalviews of a three-way valve and the controlled passages, taken on theline l 2 of Fig. 8. Fig. 7 is a side elevation of said valve; and, Fig.8 is a section thereof on the line 3 4, Fig, 6. Figs. 9 and lO aredetails ot' some of the connections, and Fig. 1l is a plan view of theseat.

A represents an elevated water-tank. c represents an outlet-pipe leadingfrom the bottom of said tank and terminating in the passages f in theshell of the valve F. (Shown in Figs. 5 and 6.)

The valve F consists of a shell having therein two passages ff', a plugF rotatable in the shell and Vhaving a water-passage therethrough and anoutlet-pipe. The passage f has two connections with the plug F', and thepassage f one connection, as clearly shown in Figs. 5 and 6, Fig. 6representing the plug in position to connect passages j and f and toclose the outlet-pipe, and Fig. 5 representing the plug in position-toclose the connection between passages f and j" and to connect passage fwith the outlet-pipe.

C represents the lid of a water-closet secured to the seat by the hingesr w, and in the arrangement illustrated I have extended the pintle w ofthe lid and connected it by a squared end w directly with the plug F asshown in Fig. 7, though this arrangement may of course be modified, asany connection by which the motion of the lid operates the valve isWithin my invention.

B represents a stand-pipe, whose lower end is connected with the passagef in valve F, and whose upper end extends above the highwater level intank A.

The pipe B is intended to contain the quantity of water to be expendedat each use of the closet.

Closing the lid C rotates plug F into the position shown in Fig. 6,establishing-communication between pipes c and B, whereby pipe B isfilled from tank A, and raising said lid rotates plug F into theposition shown in 5, opening connection between pipe B and thevalve-outlet, thus discharging the contents of the pipe B into thecloset.

To the lid C is attached an arm Q, extending through the rear part ofthe covering of the closet, this rear part being cut away on its innerside to permit the lid being closed without interference from the saidarm.

E represent-s the hopper carrying a bowl of ordinary construction.

H represents a pan fastened rigidly to a shaft h, having bearings in thehopper E,one end of said shaft protruding through the side of the hopperand having attached to it the lever I. To the lever I is swiveled aprojection 7s. The rear end of the lever I is provided with notchedteeth, as shown.

J represents a weighted swinging clutch pivoted in a framej, attached tothe upper part of the hopper F., and is provided with a weight fm, and atooth for engaging in the teeth upon the lever I.

Q represents an arm, which is attached to the lid C and moves with it,and has pivotally attached to it a gravity-operated pawl Z', having thefinger y, adapted to engage the stop 0c in such manner that when the lidc is raised and the arm moves downward the pawl will ride over thecurved bearing on the clutch J, assuming the position shown in Fig. 9.Vlien the lid is closed, the lirst few inches of its movement causes thepawl Z to force downward upon the curved bearing of the clutch J,swinging its tooth out of engagement with the lever I and allowing thepan to swing by its own gravity and the weight of its contents into sucha position as to be immediately freed from its contents.

Pivotally attached to the arinQ is a rod k. This rod passes through theprojection lo, which is attached to the lever I, and it (the rod) isprovided at its lower end with an adjustable stop l. p

As the lid moves downward after the pan IOO has been dumped by its firstfew inches ot' travel, the rod 7c is ,drawn by its attachment to the armQ through the hole in the projection k, until when the lid has passedthrough a portion of its motion the stop l on the end of the rod engageswith the projection 7c and the rest of the movement of the lid raisesthe pan H to its original position. The tooth on the weighted clutch Jthen engages with the lever I and holds the pan in place while the lidis again raised, the arm q swinging forward and the rod k passingthrough the proj ection 7c until the lid is at the end of its upwardmovement, when the parts again assume the position shown in Figs. 3, 4,9, and l0. Attached to the upper part of the hopper E is a guide p,through which passes the adjustable sliding arm 0, provided with notcheso', arranged to engage in the guide p. This arm also passes through anextension of the frame j', to which is pivoted the swinging clutch J. Inordinary use the rod ois heldin the position shown in the drawings bythe engagement of the rear of one of the notches o with the guide p; butif the water in the tank becomes at any time exhausted, the arm o, whichis provided at its outerend with a convenient handle, can be raised outof its engagement with the guide P and forced backward and engaged withthe guide P by the forward one of its notches o. This change of positionof the arm o forces the tooth on the swinging clutch J out of engagementwith the lever I, and

consequently when the lid is open the pan assumes a vertical positionand the closet can be used dry, as a free passage from the seat throughthe bowl and hopper is provided; but when the lid is closed the pan isswung upward to the position shown in the drawings, excluding the dustand cold air which otherwise could enter through the hopper and bowl.

It will be noticed that in the operation of this closet, while beingused with water or wet, the pan is always up, excepting while it isbeing dumped by theV movement of the lid from open7 to closed, and thatwhile being used dry the pan is also always up, excepting while the lidis open for use.

What I claim as my invention, and desire to secure by Letters Patent, is

l. In a water-closet, the combination, with an elevated tank and itsoutlet-pipe, of a measuring-chamber, and a valve permanently connectedwith and operated by the closetlid and alternately connecting saidmeasuring-chamber with said tank and the closet, substantially as andfor the purposes set Jforth.

2. In a water-closet, the combination, with the lid, of a multi-wayvalve permanently connected therewith and with an elevated tank, with ameasuring-chamber, and with the closet, substantially as shown anddescribed.

3. In combination with the lid of a watercloset, a multi-way valvehaving its plug connected with the end of the hinge-pintle on which thelid turns and having ports connected with a water-supply, ameasuring-pipe, and with the closet, substantially as described.

4. In a water-closet, a swinging pan normally raised, a clutch holdingsaid pan in a raised position, a hinged lid connected with and openingsaid clutch as the lid moves downward, and a loose connection betweensaid lid and pan, whereby the downward motion of said lid first dumpsand then raises the pan, substantially as shown and described.

5. In a pan-closet, a service-pan normally raised, a connection fromsaid pan to a hinged lid, whereby said pan is raised, a clutch forholding said pan raised, and a movable stop for throwing out said clutchat will, substantially as shown and described.
